+ Etterprøvbar kunnskap under press, alle mann til pumpene! +
+
+ 24th September 2012 +
+
+

Jeg har sterk tro på vitenskap, som er et annet navn på +etterprøvbar kunnskap, som metode for å sikre et velfungerende +samfunn. Eller som en fantastisk reklamekampanje i England formulerte +det, vitenskap +flyr deg til månen, religion flyr deg inn i bygninger. Men den +vitenskapelige metode trenger folk med kunnskap, evne og vilje til å +gjøre sitt beste, og settes under press av et samfunn som ikke akkurat +belønner slike egenskaper. Her er noen skremmende og oppmuntrende +lenker relatert jeg anbefaler alle å lese:

+ + + +

Ingen tvil om at alle gode krefter må jobbe sammen for å sikre at +vi vet hvor vi skal fly.

+ Seventy percent done with Norwegian docbook version of Free Culture +
+
+ 23rd September 2012 +
+
+

Since this summer, I have worked in my spare time on a Norwegian docbook version of the 2004 book Free Culture by Lawrence Lessig. +The reason is that this book is a great primer on what problems exist +in the current copyright laws, and I want it to be available also for +those that are reluctant do read an English book. + +When I started, I +called +for volunteers to help me, but too few have volunteered so far, +and progress is a bit slow. Anyway, today I broken the 70 percent +mark for the first rough translation. At the moment, less than 700 +strings (paragraphs, index terms, titles) are left to translate. With +my current progress of 10-20 strings per day, it will take a while to +complete the translation. This graph show the updated progress:

+ + + +

Progress have slowed down lately due to family and work +commitments. If you want to help, please get in touch, and check out +the project files currently available from +github.

+ +

If you are curious what the translated book currently look like, +the updated +PDF +and +EPUB +are published on github. The HTML version is published as well, but +github hand it out with MIME type text/plain, confusing browsers, so I +saw no point in linking to that version.

+ Vitenskaplig metode i politikken? +
+
+ 20th September 2012 +
+
+

Jeg ble for noen dager siden tipset om en rapport utarbeidet av +Cabinet Office i England ved navn +Test, +Learn, Adapt: Developing Public Policy with Randomised Controlled +Trials, skrevet av blant annet Ben Goldacre (som jeg først ble +klar over da han holdt et veldig interessant TED-foredrag med tittel +Battling bad +science). Rapporten handler om hvordan det offentlige burde bruke +vitenskaplige metoder i større grad for å finne ut hvilke virkemidler +som er mest effektive når en skal regulere samfunnet. Her er et sitat +fra starten av rapporten:

+ +
+

Randomised controlled trials (RCTs) are the best way to determine + wheather a policy is working. They are now used extensively in + international development, medicine, and business to identify which + policy, drug or sales method is most effective. They are also at + the heart of the Behavioural Insights Team's methodology.

+ +

However, RCTs are not rutinely used to test the effectiveness of + public policy interventions in the UK. We think they should be.

+
+ +

Her tror jeg også Norge har noe å lære. Det offentlige bruker mye +penger på aktiviteter der det ikke er åpenbart (og heller ikke blir +målt) at den reelle effekten er det en ønsker å oppnå. Ruters +elektroniske billettsystem, NAV-reformen, økt bruk av penger på +politiet og sykehussammenslåinger kommer meg i hug.

+ Debian Edu interview: Giorgio Pioda +
+
+ 17th September 2012 +
+
+

After a long break in my row of interviews with people in the +Debian Edu and Skolelinux +community, I finally found time to wrap up another. This time it is +Giorgio Pioda, which showed up on the mailing list at the start of +this year, asking questions and inspiring us to improve the first time +administrators experience with Skolelinux. :) The interview was +conduced in May, but I only found time to publish it now.

+ +

Who are you, and how do you spend your days?

+ +

I have a PhD in chemistry but since several years I work as teacher +in secondary (15-18 year old students) and tertiary (a kind of "light" +university) schools. Five years ago I started to manage a Learning +Management Service server and slowly I got more and more involved with +IT. 3 years ago the graduating schools moved completely to Linux and I +got the head of the IT for this. The experience collected in chemistry +labs computers (for example NMR analysis of protein folding) and in +the IT-courses during university where sufficient to start. Self +training is anyway very important

+ +

I live in the Italian speaking part of Switzerland, and the +SPSE school (secondary) is a very +special sport school for young people who try to became sport pro (for +all sports, we have dozens of disciplines represented) and we are +recognised by the Olympic Swiss Organisation. + +

How did you get in contact with the Skolelinux/Debian Edu +project?

+ +

Looking for Linux / Primary Domain Controller (PDC) I found it +already several years ago. But since the system was still not +Kerberized and since our schools relies strongly on laptops I didn't +use it. I plan to introduce it in the next future, probably for the +next school year, since the squeeze release solved this security +hole.

+ +

What do you see as the advantages of Skolelinux/Debian +Edu?

+ +

Many. First of all there is a strong and living community that is +very generous for help and hints. Chat help is crucial, together with +the mailing list. Second. With Skolelinux you get an already well +engineered platform and you don't have to start to build up your PDC +and your clients from GNU/scratch; I've already done this once and I +can tell it, it is hard. Third, since Skolelinux is a standard +platform, it is way easier to educate other IT people and even if the +head IT is sick another one could pick up the task without too much +hassle.

+ +

What do you see as the disadvantages of Skolelinux/Debian +Edu?

+ +

The only real problem I see is that it is a little too less +flexible at client level. Debian stable is rocky and desirable, but +there are many reasons that force for another choice. For example the +need of new drivers for new PC, or the need for a specific OS for some +devices that have specific software packages for another specific +distribution (I have such a case for whiteboards that have only +Ubuntu packages). Thus, I prepared compatibility packages educlient +and eduroaming, hoping not to use them ;-)

+ +

Which free software do you use daily?

+ +

I have a Debian Stable PDC at school (Kerberos, NIS, NFS) with +mixed Debian and Ubuntu clients. If you think that this triad +combination is exotic... well I discovered right yesterday that +Perceus +has the same...

+ +

For myself I run Debian wheezy/sid, but this combination is good +only I you have enough competence to fix stuff for yourself, if +something breaks. Daily I use texmacs, gnumeric, a little bit of R +statistics, kmplot, and less frequently OpenOffice.org.

+ +

Which strategy do you believe is the right one to use to +get schools to use free software?

+ +

I think that the only real argument that school managers "hear" is +cost reduction. They don't give too much weight on quality, stability, +just because they are normally not open to change.

+ +

Students adapts very quickly to GNU/Linux (and for them being able +to switch between different OS is a plus value); teachers and managers +don't.

+ +

We decided to move to Linux because students at our school have own +laptop and we have the responsibility to keep the laptop ready to use; +we were really unsatisfied with Microsoft since every Monday we had 20 +machine to fix for viral infections... With Linux this has been +reduced to zero, since people installs almost only from official +repositories. I think that our special needs brought us to Linux. +Those who don't have such needs will hardly move to Linux.

+ Naturvernforbundet i Oslo bruker OpenStreetmap i sin kalender +
+
+ 16th September 2012 +
+
+

Veldig morsomt å se at +Naturvernforbundet Oslo og +Akershus bruker kart fra +OpenStreetmap.org i +sine +kalendere. Vidar Gundersen i kartgruppa +forteller +på den norske epostlisten til prosjektet at hvert blad i +kalenderen har et turforslag på baksiden, med kart fra OpenStreetmap. +Tidligere kjøpte de visst kart fra kartverket, men nå slipper de +det.

+ +

Denne nyheten synes jeg er fantastisk bra, og jeg håper de får +følge av flere, slik at det potensielle og fryktede inntektstapet for +kartverket ved frigjøring av kartdata blir mindre, og forhåpentligvis +til slutt så lite at frykten for å frigjøre data overvinnes.

+ IETF activity to standardise video codec +
+
+ 15th September 2012 +
+
+

After the +Opus +codec made it into IETF as +RFC 6716, I had a look +to see if there is any activity in IETF to standardise a video codec +too, and I was happy to discover that there is some activity in this +area. A non-"working group" mailing list +video-codec +was +created 2012-08-20. It is intended to discuss the topic and if a +formal working group should be formed.

+ +

I look forward to see how this plays out. There is already +an +email from someone in the MPEG group at ISO asking people to +participate in the ISO group. Given how ISO failed with OOXML and given +that it so far (as far as I can remember) only have produced +multimedia formats requiring royalty payments, I suspect +joining the ISO group would be a complete waste of time, but I am not +involved in any codec work and my opinion will not matter much.

+ +

If one of my readers is involved with codec work, I hope she will +join this work to standardise a royalty free video codec within +IETF.

+
+ IETF standardize its first multimedia codec: Opus +
+
+ 12th September 2012 +
+
+

Yesterday, IETF announced the +publication of of +RFC 6716, the Definition +of the Opus Audio Codec, a low latency, variable bandwidth, codec +intended for both VoIP, film and music. This is the first time, as +far as I know, that IETF have standardized a multimedia codec. In +RFC 3533, IETF +standardized the OGG container format, and it has proven to be a great +royalty free container for audio, video and movies. I hope IETF will +continue to standardize more royalty free codeces, after ISO and MPEG +have proven incapable of securing everyone equal rights to publish +multimedia content on the Internet.

+ +

IETF require two interoperating independent implementations to +ratify a standard, and have so far ensured to only standardize royalty +free specifications. Both are key factors to allow everyone (rich and +poor), to compete on equal terms on the Internet.

+ +

Visit the Opus project page if +you want to learn more about the solution.
